Abstract

The aim of this study was to evaluate usefulness of ambulatory blood pressure monitoring (ABPM) to examine circadian patterns of blood pressure (BP) alterations in young, normotensive patients with type I diabetes mellitus (DM1). We studied 43 patients with DM1 aged 18-28 years, with 9-23 years of DM1, without long-term complications. Control group consisted of 32 healthy persons, matched to the DM1 group. 24h ABPM was performed by a Spacelab 90207 device to obtain daytime (7 AM to 11 PM, readings at 20-min interval) and nighttime (11 PM to 7 AM, readings at 30-min interval) measurements in both groups. During the daytime systolic BP (sBP) and diastolic BP (dBP) were not significantly different from the control group. We noted nighttime sBP and dBP higher in DM1 group: sBE 119.7+/-12.6 mmHg vs. 103.817.1; p = 0.001 l dBP 65.5+/-6.2 vs. 61.5+/-3.1; p = 0.001. The loss of fall in BP ('non-dippers') was more prevalent in DM1 group: 49% vs. 9%; p = 0.003. Pulse pressure (PP) was significantly higher in DM1 patients: 50.9+/-6.9 mmHg vs. 44.8+/-5.6 mmHg; p = 0.0001. ABPM is a useful method in detecting early BP alterations in young normotensive patients with diabetes mellitus type 4 1. Increased PP and suppressed diurnal BP variation...Continue Reading
